Underdog teams topple baseball's caste system. "[T]his postseason shows that the savviest can survive – and even succeed – in a sports world run by big spenders. 'The nature of the game is to have some imbalance, but the question is whether the imbalance has gotten to the point that rich teams can win and poor teams can't,' says Jules Tygiel, author of 'Past Time, Baseball as History.' He adds, 'This postseason has shown that is not the case.'" (Christian Science Monitor)
